Introduction
Roofing materials play a crucial role in determining the durability, energy efficiency, and overall maintenance of a home. In Malaysia, where the climate is hot, humid, and prone to heavy rainfall, choosing the right roofing material is essential. While asphalt shingles are a popular choice in Western countries, they are not widely used in Malaysia. This is due to several factors, including their poor heat resistance, shorter lifespan in tropical conditions, vulnerability to strong winds, higher costs, and the preference for more durable alternatives like metal and clay tiles.
1. Unsuitable for Malaysia’s Hot & Humid Climate
Malaysia’s tropical weather, characterized by high temperatures and humidity, makes asphalt shingles a less desirable option. These shingles absorb and retain heat, increasing indoor temperatures and raising cooling costs. Unlike more reflective roofing materials, such as metal, asphalt shingles contribute to excessive heat buildup. Additionally, high humidity levels encourage the growth of mold, mildew, and algae, which deteriorate the shingles over time and affect their longevity.
2. Shorter Lifespan in Tropical Conditions
Although asphalt shingles typically last between 15 to 30 years in cooler regions, their durability is significantly reduced in Malaysia. The intense exposure to ultraviolet (UV) rays causes the shingles to dry out, crack, and curl, leading to faster wear and tear. Frequent heavy rain also washes away the protective granules on the shingles, making them more prone to leaks and structural damage. This results in higher maintenance costs and a shorter overall lifespan compared to other roofing materials.
3. Poor Resistance to Heavy Rain & Strong Winds
Malaysia experiences frequent thunderstorms and strong winds, especially during the monsoon season. Asphalt shingles, being lightweight, can be easily lifted or torn off by strong winds, making them less reliable. In contrast, materials like clay and concrete tiles, which are heavier and more securely fastened, provide better protection against extreme weather conditions. The impact of wind-driven debris and heavy rain further weakens asphalt shingles, increasing the risk of damage and water leakage.
4. Availability & Cost Concerns
Unlike metal or clay tiles, asphalt shingles are not as readily available in Malaysia, making them a less common roofing choice. Due to lower demand, they often need to be imported, which raises costs. Furthermore, their shorter lifespan and higher maintenance requirements result in long-term expenses that outweigh their initial affordability. As a result, homeowners find it more cost-effective to invest in durable roofing options that require fewer repairs and replacements.
5. Preference for More Durable Materials
Given Malaysia’s challenging weather conditions, homeowners prefer roofing materials that offer greater durability and protection. Metal roofing is a popular choice due to its excellent heat reflection, long lifespan of 40-70 years, and energy efficiency. Clay and concrete tiles are also widely used for their durability, fire resistance, and ability to withstand tropical weather. These materials provide better insulation, require less maintenance, and ensure long-term reliability, making them more suitable for Malaysian homes.
6. Environmental & Maintenance Considerations
Asphalt shingles require regular maintenance due to mold and algae growth, which increases cleaning and repair costs. Additionally, they are less environmentally friendly because they contain petroleum-based materials and have a shorter lifespan. In contrast, metal, clay, and concrete roofing options are more sustainable, with longer durability and better recyclability. With Malaysia’s growing focus on energy efficiency and sustainability, many homeowners are choosing eco-friendly roofing solutions that reduce long-term environmental impact.
Conclusion
Although asphalt shingles are widely used in many countries, they are not well-suited for Malaysia’s climate and weather conditions. Their poor heat resistance, short lifespan, vulnerability to strong winds, and higher maintenance costs make them a less practical option. Instead, Malaysians prefer more durable and energy-efficient roofing materials such as metal, clay, and concrete tiles, which offer better protection and long-term savings. As roofing technology advances, the focus remains on materials that provide sustainability, durability, and cost efficiency, making asphalt shingles an uncommon choice for Malaysian homes.
